    Bonding Polycarbonate (Lexan)

    I would normally recommend an acrylic adhesive. 3M & almost everyone makes them. Typically it will be a PSA. Good luck, John Schrock www.glubie.com

    PSA, bonding neoprene foam to acrylic

    Dave, You are right about there being several PSA's. At last count we've had almost 20 in stock. The problem that you are having w/ finding a white one is the composition. Invariably you will either have a PSA that dries clear or an amber colored one. I hope I've helped, John Schrock...

    Adhesives for difficult substrate combo

    My first guess would be a CA (cyanoacrylate) or an acrylic transfer tape that Dave mentioned. You may try using a urethane as a low cost bond. I hope I've helped, John Schrock www.glubie.com

    glulam beams

    Do not use Titebond or the equivalent. The aliphatics have horrible resistance to water. Even the Super Titebond was not designed for submersion. Use a structural urethane (used commonly in RV mfg to bond sidewalls to aluminum studs. Cure time is approx. 4 hours. Will be impervious to the...

    Need glue to attach wood veneer to thin wood panels

    Roger, You are completely right about the moisture in the adhesive causing this problem. Most waterbased glues (Titebond "aliphatic", Super Titebond "PVA") contain upwards of 50% water to act as the carrier. If the wood wasn't porous, it wouldn't cause as much of a...

    Adhesive for polycarbonate sheet.

    I would suggest using a urethane adhesive. It bonds to almost everything and gives structural support. The only time that I have witnessed failure was in the presence of oil. I hope I've helped, John Schrock www.glubie.com

    bonding neoprene drive belt

    The two materials I would have you try are: 1. Compounded Neoprene contact adhesive 2. Polyurethane Reactive PUR The Neoprene contact adhesive is flammable, but will probably take the heat. The PUR will also give you excellent bonding power w/ flexibility and quick cure. I hope that...

    Silicone adhesion to fabric

    The problem with using silicone is the weak bond strength. Do you require high temperature resistance for this device? If you do not, I would suggest switching to a low cost moisture cure urethane that will provide an exceptional bond to the fabric with all the flexibility required. It has...

    Hot Melt Adhesives for Fabric

    Kaleem, Without knowing your location, it is hard to refer a vendor. I would recommend a hot melt called HL-0747HS for this application. It provides a structural bond approved by auto manufacturers. Depending on the application, I would either suggest a roll coater or spray head to apply...

    Wood on stainless steel

    I would suggest a SMP (Silyl Modified Polymer). It's adhesion competes w/ a methacrylate for structural strength. It also has incredible flexability. It can stretch up to 200% of the bond line and still maintain a structural bond. It is impervious to weather and comes in an easy to use caulk...

    connecting polyurethane to aluminium

    You can accomplish this bond with a moisture cure urethane. It will bond exceptionally well to both materials. I hope I've helped, John Schrock www.glubie.com

    Bond/epoxy for cleanroom, stainless steel to ???

    I am presently unsure if this is qualified as "clean room safe", but Moisture cure urethanes provide all the qualities listed. Flexibility up to 200% elongation (no cracking, flaking), excellent adhesion and strength. I hope I've helped John Schrock www.glubie.com

    I'm looking for a "wet Condition" sealant

    Roy, Good News! You can use an inexpensive Moisture cure urethane to stop that leak. These urethanes are recommended for above or below the water line in the Marine industry. The water will accelerate the cure and you will have a strong bond. Epoxy was not the best choice due to the wet...

    Positioning a rotating basket precisely to the same position each time

    I think ve7brz may be on the right path. The problem that I have had w/ photo sensors has been with refining accuracy. The photo eyes that I have used are good to within 12" for a large target. You can compensate for this by going to the fiber optic accessory. You would have to...

    What is the best stainless steel adhesive?

    Methacrylates are an excellent adhesive, but very pricey. You will get a stronger bond with a MA but in most cases it's overkill unless you are using it as a support. I do not try to push an individual product, which is why I never call it by name on a response. Several manufacturers make...

    Seeking a cast iron reparation method without welding

    I believe the product you are looking for is called "quick metal". It is used for a variety of applications and appears to be what you need. Good Luck, John Schrock www.glubie.com

    Bonding wood on stainless steel

    To bond stainless, copper, brass etc. to wood for knife handles I would use a 2-part epoxy. The reason for this is that knives will go into the sink or dishwasher so they must have good water & heat resistance. They will be used to cut, so it must have excellent strength. It must also have...

    Need to adhere copper sheet to wood covered with cured epoxy. How?

    Hopefully the epoxy wasn't too expensive. You have a couple of different options for bonding the copper, and a couple that I would like you to avoid. Promise me that you will not use a silicone based product!! The acetic acid that is released during its cure will corrode the copper. The ways...

    N Propyl Bromide Adhesive - Need replacement

    I am looking for a replacement adhesive for NPB. This adhesive is on the suspect list for toxicity, but appears to be the only alternative to a non-flammable spray adhesive. My only avenues at this point are Waterbase (which will not work well since the substrates are both FRP). Flammable...

    silicone in automotive industry?

    Silicone has gotten a bad name due to its curing process. Most silicones free acetic acid, which will prevent painting, corrode brass & copper, and a few other minor effects. If heated over 150F degrees most will release formaldehyde fumes. Most Silicones will degrade catalytic devices used...
